season and last week showed that with all BYU's RBs back that it will likely improve. OSU has been terrible in rush defense this season.
OSU also has not been able to run the ball at all this season, they are averaging like 3.4 a carry, that's worse than BYU last season. I believe rain and sloppy field would benefit BYU in this game. As long as they wear the right spikes.
